A photopolymerizing composition and a photopolymerizing recording medium manufactured using the composition, wherein the photopolymerizing composition contains: 1.0-99.0% by weight of at least one kind of polymerizable compound; 0.05-0.5% by weight of at least one kind of photosensitizer selected from among photochromic compounds that change color by incoherent UV light irradiation; 0.2-6.0% by weight of a coinitiator that is activated by visible light in the presence of a photoinduced form of the photochromic compound transformed by incoherent UV light to photopolymerize the polymerizable compound; 0-97.5% by weight of a polymer binding agent; 0-6.0% by weight of a plasticizer; and 0-3.0% by weight of a non-polymerizing solvent. The photopolymerizing recording medium has a high angular diffraction selectivity and thus can be effectively used to manufacture a 3D holographic optical memory with ultra high information storage capacity.
